Following message is displaced in the Installation Log file:

WARNING:

The LISTENER from Grid Infrastructure home is running fine:

Same error is observerd by manually runnig CVU as:

WARNING:

Verification of SCAN VIP and Listener setup failed
Verification of scan was unsuccessful on all the specified nodes.
Checking the status of SCAN using SRVCTL gives correct results:
$ srvctl config scan
SCAN name: scan-test.abc.com, Network: 1/165.101.124.0/255.255.254.0/eth0

		<description><![CDATA[I am creating 11gR2 RAC setup for one of my client. Following Oracle documentation for storage, I opted for Oracle ASM and asked storage team for new physical devices.
Storage admin thus provided me with a set of LUNs instead of actual physical device names like /dev/sdcxxx.
Now the major task is to get the actual device name associated with LUNs.
In OEL4 this is easy to get by issuing 
# iscsi-ls -l
This command will give output like:
DEVICE DETAILS:
---------------
LUN ID : 0
Vendor: DELL     Model: MD3000i          Rev: 0670

		<description><![CDATA[11gR2 introduced renamedg utility to rename diskgroups. I would discuss renaming a diskgroup on a Standalone Grid Infrastructure installation with Oracle Restart. Before you use the command, ensure that ASM diskgroup is dismounted.
Below is syntax for the command. You can refer to 11gR2 docs for details
renamedg
[phase={ one&#124;two &#124;both } ] dgname=diskgroup
newdgname=newdiskgroup [config=configfile]
[ asm_diskstring=discoverystring, discoverystring ... ]
[ clean={true&#124;false} ] [ check={true&#124;false} ]
[ confirm={true&#124;false}] [ verbose={ true&#124;false} ]
[ keep_voting_files={true&#124;false}]
Basically we have two phases of using renamedg command, phase 1 generates a configuration file to be used by phase 2. In phase 2 actual renaming of diskgroup is done.
Note : &#8211; I have tried these steps in a Test environment and tried to cover the most components. But would recommend you  to cross verify the steps in a test environment before implementing in production environment
Lets get Started!!
1) Gather all the information for Oracle restart Configuration and DB parameters

		<description><![CDATA[SYSASM role was introduced in 11gR1 and was designed to administer ASM instances. In 11gR1 , if you connected with SYSDBA role , you used to get a warning which was only recorded in alert log (Refer to my earlier post here). But things have changed in 11gR2. While trying to dismount a Diskgroup, I found following errors
SQL&#62; alter diskgroup flash_arc mount;
alter diskgroup flash_arc mount
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15260: permission denied on ASM disk group
Above error indicates that I do not have permission on the ASM Diskgroup.  As per 11gR2 documentation, SYSASM privilege is used for carrying out administration tasks on ASM Diskgroups. SYSDBA privilege can be used only for creating/deleting aliases and querying ASM dictionary views.  Frankly speaking, you should unlearn the habit of connecting as &#8220;/ as sysdba&#8221; to ASM instance and learn connecting as &#8220;/ as sysasm&#8221;

		<description><![CDATA[Short post on a issue faced by me, while starting up a cloned database
SQL&#62; startup nomount
ORA-24323: value not allowed
ORA-27146: post/wait initialization failed
This database environment was cloned and was being started for first time after cloning. Running hcve scripts on system indicated that OS kernel parameters were adequately sized.
SHMMNI set to 1000 is adequate
SHMSEG set to 120 is adequate
SEMMNI set to 700 is adequate
SEMMNS set to 2000 is adequate
MAX_THREAD_PROC set to 256 is adequate
NFLOCKS set to 1450 is adequate
My Oracle Support articles suggested this issue is related to semaphores setting. As settings were correct, I attempted to start instance by commenting processes parameter in init.ora (setting was 1000). This time database started.
I modified the processes parameter back to 1000 and attempted to restart the Database. It started  again!! I am clueless on why it initially failed and then started with same setting. Does anyone have any reasoning for this behavior?
